RESUMO
Loops and braids in filaments of the cyanobacterium Mastigocladus laminosus were observed. Braided filaments were generally in the form of a right-handed helix (87%) but were occasionally observed as left-handed helices (13%). It was demonstrated by time-lapse photomicrography that braids continued to grow as braids and that loops coiled into braids as growth proceeded. Measurements of the distance between grooves in 74 braids yielded an average distance of 13 +/- 3 micron, a result which suggests that braid formation is not random. We propose that the braids arise as a consequence of the helical growth of cells that make up the filaments of M. laminosus.
